Homebrew RELEASE Clean the Nand of the Nintendo Switch, Haku33 homebrew

grcd · Jan 13, 2020

So, will this truly make the installation of CFW - even games/homebrew installed on the internal NAND complete undetectable post-wipe? Wouldn't Nintendo be able to detect this tool had been run merely by virtue of so many critical files missing or being wiped? Just want to ensure this is 100% safe and undetectable rather than too destructive to be useful.

It is not sure whether installation simply of homebrew without installing games wouldnt lead to a ban.

RIght now you can:

1. Back up your save files using checkpoint (just to be safe)
2. Create an emunand on sd card partition (search for the steps, you need at least 32gb of free space)
3. Do this method (this thread) to clean your sysnand (since you don't have clean nand backups, this is your only choice so far)
4. Your sysnand will now be clean (hopefully) and you can start fresh with your games and play online. On top of that, you have emunand where your saves are stored, where you can install anything you want

Excuse the second post in a row, but I have a question on this:

Wouldn't that technically mean you can be traced if your emunand ever accidentally logs to a Nintendo server? I'm using of course all measures including DNS, but I'm just curious as I've never used emunand and was always reluctant because I felt it would add another layer of complexity.

There are people claiming that they have not yet been banned YET (including myself), and there's no guarantee that the ban hammer (EDIT: will to won't) won't affect us too. But there is no other choice for those who don't have clean nand backups.

You can wait and see if someone will get banned after using this, or you could be one of us to try it out and risk it.

Again, this is only useful and the only choice (for now) for those who do not have clean nand backups.

Look at it like this. You have a nintendo switch with its own operating system in its own drive.
You copy that operating system into a different drive (your sd card)
and that will be your emunand and leave the sysnand untouched.

When your emunand bricks, you are safer, because you can always create another based on the sysnand.
But if you dont use emunand and manage to eff up your sysnand, then you are unlucky if you don't have a nand backup.

It is important that your emunand will never connect to nintendo's servers, but your sysnand, since it is clean, is safe to connect Nintendo's servers.

This tool has become a must for me, I always use this before setting up a Switch for a client or my friends. Before that I always had to mount the nand and carefully remove everything related to the use of a CFW, but now it's really simple.
Still, I would recommend you to make a rawNand backup before using it, just in case your Switch reboots during the process.
If you intend to hack your Switch for the first time and don't plan to use emuMMC, just follow these steps :
- Make a rawNand backup from Hekate or using NxNand
- Boot your Switch on airplane mode with AMS for the first time, and use Checkpoint to backup your saves on the mSD
- Use Haku33 to wipe the Switch, then power it off and start it on recovery mode to wipe it again the official way
- Optionnal : create emuMMC
- Use Incognito_RCM to remove the Profinfo
- Boot it with AMS and configure it from scratch and restore all your savegames

You won't have to worry about connecting it to wifi or whatever

What is the use of removing prodinfo btw? Im not really familiar with it

It is meant to "anonymize" your Switch by removing most of the system informations that makes it different from other units to Nintendo on internet. If you use Incognito, Incognito_RCM or NxNand for this purpose, you will see that your S/N will not appear on your Switch settings, and you won't be able to connect it to any Nintendo service nor update it without ChoiDuJourNX.

By doing this, you won't have to avoid your Switch to connect to the web or to configure 90DNS every time you add a Wifi access point to your Switch.

Thought removing your PRODINFO doesn't makes your Switch 100% invisible, this it, to me, the best way to be safe when using it online. But don't forget to keep a rawNand backup on a safe place and a backup of your PRODINFO partition too.

After 8 months of using my Switch with its PRODINFO blanked, I tried connecting it to my Nintendo account and I did not have any ban related error.

We will see if all this is efficient or not when Nintendo will start a new big ban wave...

Oohh okay thanks a lot! I'll try this out soon

what are the chances of still getting banned after using this?

ceanth · Jan 24, 2020

Hi all,

I have a switch which I did not make a clean backup off so considering using this tool.

Am I right that I would loose my current saved games or is there a method to either keep or restore saved games?

lucas millington · Jan 28, 2020

didnt work, still banned after using this

As in you were banned before this process and your still banned or you were not banned and are now banned?

Because they ban your console, not a file on your system. I already warned you about this in a previous thread. If you EVER connected to Nintendo before, it was just waiting for a ban using this tool.

im confused, are you saying that this user went online prior to applying this hence the ban? So the ban has nothing to do with the clean nand tool?

Let me break down, because I never really understood OP before.

But he wanted to clean his nand, since it was dirty. He wanted to play Splatoon 2.
I told him if he doesn't have it clean nand backup, you can never go back. Haku33 is probably the best chance he got. BUT if he evern been online with the Switch to Nintendo, before using this tool. He would be banned. Since he now have deleted logs etc. that Nintendo already had. Proving he use a modified system.

MADokax · Jan 30, 2020

Hi everyone
I used this tool on my boyfriend console and mine (He didnt have a NAND backup, so this was our only option) we always used 90dns all the time! all of this on CFW Sysnand
we created an Emunand so we could play our original games online again! and with haku33 we did it, I didnt restore my nand backup, I just used haku33 and everything workd fine

so yeah, haku works completely and you can go back to online with it!

I had to use the older version (the NSP one) because the latest nro didnt work

thank you

also I have been with cfw on my clean stock sysnand to inject pokemon saves, and the last week I accidentaly entered eShop with CFW, I´ve never been banned

grcd · Jan 30, 2020

If you just accidentally went to the eShop last week that doesn't mean you won't get banned. Bans do not happen immediately but in waves

MADokax · Jan 30, 2020

I have been online with cfw in 2018, nothing happened with me
it was when ReiNX was just released

>removing most of the system informations
It only deletes the ssl certificate and serial number afaict, which isn’t even 1/10th of the info stored in cal0 kek

the tool is not going to unban you . It works to clean the nand in case you are not ban and do not have a clean backup

....
Haku33 is for consoles that not have a clean nand backup
consoles in that situation do not have many options, you can leave it offline and never connect to Nintendo or use Haku33 or hack disk mount to clean the nand

That's more than enough for this purpose, so what's the point ? You want to blank WlanMacAddress and AmiiboKey too ? "kek"
